This storage site consists of 1 cell located <br />within the area of the Transit Mix East Pit as identified in the June 5, 2009 liner test plan. At this time there hasn't been <br />any specific mention of any storage in this vessel. <br />This approval is based on the site inspection conducted on October 19, 2010 and on the information provided by you <br />under a cover letter dated April 15, 2010. The measured outflow due to pumping indicate that this site has been fined to <br />the desiwn standard referenced in the August, 1999 Slate Engineer Guidelines for Lining Criteria for Gravel Pits. <br />Meeting the design standard requires that all water inflows and outflows for this site must be accounted for on at <br />least a monthly basis. <br />Please call me if you have any questions. <br />Enclosure <br />DEPARTMENT OF NATURAL RESOURCES <br />DIVISION OF WATER RESOURCES <br />January 9, 2012 <br />Sincerely, <br />ede <br />Bill W.
